2015 Audi A4 / S4 — Owner's Manual
You can also press the accelerator pedal down to increase your speed, e.g. if you want to pass someone. The speed you saved earlier will resume as soon as you let off of the accelerator pedal. If, however, you exceed your saved speed by 6 mph (10 km/h) for longer than 5 minutes, the cruise control will be turned off temporarily. The green symbol in the display turns white.
The saved speed remains the same. The speed you saved will be retained if the cruise control has been switched off temporarily. To resume the saved speed, let up on the brake or clutch pedal and pull the lever to position. Switching the ignition off erases the saved speed.
The automatic transmission is controlled electronically. The transmission upshifts or downshifts automatically depending on which drive program is selected. When a moderate driving style is used, the transmission selects the most economical driving mode. It will then change up early and delay the downshifts to give better fuel economy.
The transmission switches to a sporty mode after a kick-down or when the driver uses a sporty driving style characterized by quick accelerator pedal movements, heavy acceleration, frequent changes in speed and traveling at the maximum speed.
